npc_destroy_unselected

The npc_destroy_unselected console command is a debugging tool that destroys all unselected NPCs. To select NPCs, use the npc_select command. Destroyed NPCs are silently removed, so outputs such as "OnDamaged" and "OnDeath" are not fired, nor are ragdolls created. Destroyed NPCs carrying weapons will drop the weapon before removing themselves.

This command flags NPCs with a note to destroy themselves, so if AI is not running (due to the ai_disable command), the command will be ignored.
